We do not need to templatize the output type - it's always `float`.
Also, the input type can be inferred. Finally, use template
specialization instead of a conditional to deal with same type input and
output matrices.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Many of these functions will treat the 'pointer' parameter as an offset
into a buffer if one is currently bound.
This makes it possible to run ClassiCube with OpenGL 1.5 support!
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
According to the OpenGL 2.0 spec § 2.8, the data for each attribute type
pointer is normalized according to the type. The only exception to this
is `glVertexAttribPointer` which accepts a `normalized` parameter, but
we have not yet implemented that API.
According to the spec, enabling the client-side vertex array should
behave as if `glVertex` is executed after all other states such as the
normal, color, etc. have changed. We were not changing these states if
the client-side vertex array was disabled which probably does not affect
a lot of applications, but this seems like the correct thing to do. :^)
According to the spec, pointers to client data need to be dereferenced
immediately when adding calls such as `glDrawElements` or
`glArrayElement` to a display list. We were trying to support display
lists for these calls but since they only invoke _other_ calls that also
support display lists, we can simply defer the display list
functionality to them.
This fixes the rendering of the ClassiCube port by cflip.
Destruction of `GL::GLContext` resulted in the destruction of
`GPU::Driver` _before_ the destruction of the allocated textures, which
in turn point to `GPU::Image` objects. Since the destruction of
`GPU::Driver` unloads the shared library, we were trying to invoke
non-existing code.
Fix this by moving `m_driver` up in `GLContext` so that it's last in
line for destruction.
Propagate errors in places that are already set up to handle them, like
WebGLRenderingContext and the Tubes demo, and convert other callers
to using MUST.
When using vertex attribute pointers, we default the Q coordinate for
textures to 0 causing issues if the 4th coordinate is not passed in the
vertex data.
Clean up these defaults and make sure that Q is always set to `1.f`.
Each texture unit now has its own texture transformation matrix stack.
Introduce a new texture unit configuration that is synced when changed.
Because we're no longer passing a silly `Vector` when drawing each
primitive, this results in a slightly improved frames per second :^)
